Subject: Bluetooth: Convert BCM92035 support to driver setup callback
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=936009976497e1e123f3223bedca25312ee20f08;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: Convert BCM92035 support to driver setup callback

With the early init stage during setup, this quirk can be simplified
and kept fully inside the driver.
